(svn r6369) -Fix (r5886): On loading of game in scenario editor the player was given
the maximum amount of money so everything can be removed for sure. However
if first rails are removed (or property in general that *gives* money
when demolished, the player's money would overflow. Thanks for noticing Rubidium.
